Question

A bike rider has to cover a distance of 400 km in 10 hours. If he covers half of the journey in 60 percent of the total time. What should be its speed to cover the remaining distance in the time left?​

Answer 1

Answer:

50km/h

Step-by-step explanation:

remaining time to travel=total time-60per of total time=4h

remaining dis to travel=total dis-1/2 of total dis=200km

speed=dis/time=200/4=50km/h

Answer 2

Given: A bike rider has to cover a distance of 400 km in 10 hours. He covers half of the journey in 60 per cent of the total time.

To find: We have to find his speed to cover the remaining distance in the time left.

Solution:

We know that,

Distance=speed×time.

60% of the total time is equal to 10×60/100=6 hours.

He covers half of the journey is 400/2=200 km in 6 hours.

The remaining distance to cover=200km.

The remaining time is 10-6=4 hours.

Let his speed be x.

So, we can write-

$200 = 4x \\ x = 50$

The value of x is 50.

So, his speed should be 50km/hr to cover the remaining distance in the time left.
